iot: Explained: What is electronic paper display technology and how it can enhance IoT application

Electronic display technology or ePaper The display can mimic the look of the paper on the device’s display. Were popularized by EPDs or ePaper displays Amazon Kindle. The dual-static nature of this display technology allows it to be used in devices that do not have a conventional power budget. LCD. Recently, such reports came Apple Planning to use EPD Technology in foldable iPhones And IPad. Here we will discuss how EPD works and how this can help enhance the display IoT Applications
How does EPD work?
ePaper displays or EPDs are equipped with small capsules filled with charged ink particles that use the same ink as the traditional printing industry. When properly charged, EPD produces highly detailed images with a contrast ratio and readability of the printed material.
How is EPD different from traditional LCD?
As discussed above, this display has a bi-static nature. The dual-static display, also known as the zero power display, has a unique feature that allows the image placed on the display to remain indefinitely without being refreshed. However, traditional LCDs require screen refreshing – both active matrix displays such as TFT LCD and passive matrix displays such as monochrome character LCD. The EPD consumes power only when the screen is refreshed while the reflective LCD continues to consume power to keep the image on the screen.
How can EPDs help advance IoT?
Due to the dual-static properties of the display, the EPD can operate with extremely low power input. This display does not require extra power to retain the displayed image once the EPD text and images have been rendered. The ePaper display works at such a low power that extra energy can be used to perform updates. This extra energy enables the use of RFID or no NFC Devices with EPD without battery.
EPD can be used to enhance many IoT applications, including logistics, manufacturing and retail. Manufacturers can add these thin, lightweight, highly readable ePaper displays to highly power-related devices.
EPDs can be connected wirelessly to electronic shelf labels in retail locations. This will allow remote or central management to adjust prices for dynamic pricing strategies.
ePapers can also improve the logistics and manufacturing application of IoT devices as it provides visibility into RFID / NFC tag data at a glance.
In addition, EPDs can improve the usability of many battery-powered IoT devices, such as utility meters, cold-chain temperature data loggers, and environmental sensors.
Other benefits of using EPD
Some of the advantages of using ePaper display are – Ultra-low power consumption, bi-static property and NFC / RFID energy-harvesting capability mentioned above. In addition, EPD serves other purposes. This also provides high readability outside of the display which makes it suitable display technology. Ebook Purpose EPD can also be used in devices that have a thin and lightweight form factor, which is one reason why Apple may use this display on foldable iPhones and iPads. Additionally, the ePaper display is available in three colors for manufacturers to experiment with their device displays.
